Yes. It has been done this way since the first ones.
Keeping the atmosphere breathable is a tricky business. Among other
things, they run the air through a burner to get out old socks smells
and other undesirable traces.
I don't have a reference, but there was one where the cork insulation
on the inside of the sub had been attached with a glue using CH3Cl as
a solvent. It out-gassed and produced HCl when it went through the
burners. Of course subs are wet inside so there was dilute
hydrochloric acid everywhere. The sub was very nearly junk by the
time it came in from the first curse.
PS. looked around with the search string nuclear submarine methyl
hopcalitel hydrochloric acid
and found this
"Passage of methyl chloroform contaminated air through the submarine
CO/H 2 catalytic
burners results in the breakdown of the solvent to form vinylidene chloride and
hydrochloric acid. The latter compound, generated slowly but
continuously over a long
period of time, caused extensive corrosion damage aboard several
submarines in areas
surrounding the burner discharge before its identity and ultimate
source were discovered."
